ummm. actually i do floss alexs' but not like i do my own, i'm not getting between every tooth. when he sees me flossing my own, he waits till i can turn and holding a piece of floss (unflavored tape type) between my fingers about a foot apart he leans forward and gently bites it i release one end and pull the tape out of his mouth and we do this for a few minutes each day. and sometimes the tape gets gunky with food particles. he like this better then the tooth brushing.
